What is meq/L of 212 mg/L of Ca+2?
The valance of Ca2+ ion = its charge number = 2
So Equivalent mass = mass / valence
= 212 mg / 2
= 106 meq
So the concentration of Ca2+ = 212 mg/L
= 106 meq /L

Ca(OH)2 is added to water to reach a concentration of
53 mg/L. Initially, the water had 3.09 mg/L of Mg2+ and
it reacts with Ca(OH)2 according to equation 61a. Assume
SO4-2 is in excess. What are the final
dissolved Ca2+and Mg 2+ concentrations? What
is the initial and final hardness? What is the Mg(OH)2
precipitate concentration? (28.6 mg/L, 0 mg/L, 12.5 mg CaCO3/L,
71.5 mg CaCO3 /L, 7.28 mg/L).
